It is an important approach for achieving secure physical layer transmission using beamforming technology of multi-antenna, most of the transmission models are built on the perfect channel estimation model. The paper studies the secure physical layer transmission of multi-antenna beamforming with imperfect channel estimation information (CSI) and discusses the realization of the physical layer security...
This paper investigated unconditional secure communications in a passive eavesdropping (PE)wireless environment via a two-step method under Wyner's model. Firstly, with MIMO transmit beamforming, one can utilize the spatial degree of freedom (DoF) to cripple eavesdroppers' interceptions even though the eavesdropper's CSI is unknown. Consequently, note that the legitimate receivers will still continue...
